Fuel atomization and dispersion phenomena depend heavily on the ambient pressure and temperature. So in this work, to study diesel sprays, an electrically heated, constant volume, pressurized vessel was designed and manufactured. The control领 electronics and software were developed and tested to ensure safe and precise operation. A commercial six-hole automotive Diesel injector was used. Spray tip penetration and cone angle have extensively been used to qualify fuel dispersion and these parameters were quantified in this work using a high speed shadowgraph technique. It was observed that the temporal spray tip-penetration did not follow a time-square-root law. 阴影法激光粒径分析仪
